Origin: Native
selected vouchers: WS
Notes: A May collection by C. Bjork near Goldendale existed at WS based on specimen records in the Consortium PNW Herbaria database (accessed 12/1/21). However, a search of the collections for that specimen did not locate it. In the absence of the specimen, and the unlikelihood that a May collection would have the diagnostic fruit characters, this species is considered excluded from the Washington flora. Not reported for WA by FNA.
